== Notes and version constraints ==<br />
* The exact function of BS3 depends on soldering; please verify before configuring<br />
* When using the Bookworm OS, only the lgpio library is usable; BCM2835 and WiringPi cannot be installed<br />
* The OLED will not display images without active control from the controller device<br />
* Prolonged display of the same image may cause afterimages<br />
* Do not apply reverse voltage<br />
